Yawcam

Hi, I installed Yawcam, I opened the necessary doors and everything worked ok, remotely could see the cam. Then I saw that the program could run as a background service, very useful thing to me, however, by turning it as a service can not connect more remote. I removed fireware and antivirus but it's not. The program runs but does not make me be accessed from outside. I get it off as a service can not access easily. I do not know if the doors with the services in the backround are configured differently .... I trust in you experts ... or perhaps to demand super experts. Thank you
